I will be shocked if PS4 takes August. The samsung tv deal should secure XB the win.
But deal was in limited amount and not huge amount.
Two words: Front Loaded
XB Halo bundle is at #15 Hourly the bundle hasn't been in the top 100 for a while. I suspect it'll drop to #20 for August's monthly and fall to #50 in September. Then pick up in sales before launch in October.
Btw. where you saw now Halo 5 bundle at #15 on hourly chart? I don't see any.
